MECHANICAL MOVEM ENT.

SPECIFICATION forming part of Letters Patent No. 483,041, datedSeptember 20,1892.

Application filed April 30, 1892. Serial No. 431,342. (No model.)

To aZZ whom it may concern.-

Be it known that I, PETER A. BOUCHET, of Merced, in the county of Mercedand State of California, have invented a new and Improved MechanicalMovement, of which the following is a full, clear, and exact descripion.

The object of the invention is to provide a new and improved mechanicalmovement, which is simple and durable in construction, very effective inoperation, and more especially designed to conveniently convertreciprocating motion into rotary motion, at the same time avoiding alldead-center positions.

The invention consists of certain parts and details and combinations ofthe same, as will be hereinafter described, and then pointed out in theclaims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan view of the improvement. Fig. 2 is a sectional sideelevation of the same on the line 2 2 of Fig. 1, and Fig. 3 is a planView of a modified form of the improvement.

The improved mechanical movement is mounted on a suitably-construcedframe A, in one standard of which is journaled a shaft B, carrying atits inner end a socket or sleeve 0, in which is fitted to slide a bar D,pivotally connected with the wrist-pin E of a crankarm F, attached tothe end of a shaft G, mounted to turn in suitable hearings in the otherstandard of the main frame A.

The centers of the shafts B and G are eccentric to each other, asplainly shown in Figs. 1 and 2, so that the distance of the center ofthe wrist-pin E from the center of the shaft G is considerably less thanthe distance of the said wrist-pin center from the center of the shaft Bat the time the several parts are in the position shown in Figs. 1 and2. With the wrist-pin E is connected a link H, also connected with atreadle I, fulcrumed in the lower part of the frame A, as Will bereadily understood by reference to Fig. 2.

A pulley or crank-wheel J is attached to the outer end of the shaft Bfor rotating the latter or for transmitting rotary motion given to theshaft B. Now it will be seen that when the operator actuates, forinstance, the treadle I the crank-arm F is caused to swing, turning theshaft G, and by the swinging motion given to the crank-arm F the shaft B1s turned as the latter is connected by the sleeve 0 and the sliding barD with the wrist-pin E of the said crank-arm F.

It will be seen that when the several parts are in the position shown inFig. 2 considerable leverage is gained for the shaft B, owing to thedifference in the distance between the shafts B and G and the center ofthe wristpin E. As illustrated in Fig. 3, a series of such mechanicalmovements shown in Figs. 1 and 2 and described above can be connectedwith each other.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. A mechanical movement for convertingreciprocating into rotary motion, comprising a shaft having a socket onone end, a reciprocating bar working in said socket, and a crank-armpivotally connected at its outer end with the end of said bar and havingits center eccentric to the center of the said shaft, substantially asset forth.

2. A mechanical movement for converting reciprocating into rotarymotion, comprising a shaft having a socket on one end, a reciprocatingbar working in said socket, a crankarm, a wrist-pin pivotally connectingthe bar and crank-arm, and a link or pitman con-- nected to saidwrist-pin, substantially as set forth.

3. A mechanical movement for converting reciprocating into rotarymotion, comprising the frame A, the shaft B, having a pulley J and asocket O, a reciprocating bar D,sliding in said socket, a shaft G,parallel with shaft 13 and having a crank-arm F, provided with awrist-pin, pivotally connecting it with the said reciprocating bar, atreadle I, and a link or pitman H, connecting the treadleI'and the saidWristpin, substantially as set forth.
